4663973 Loader Fuel Hose for ZW220-6

The original fuel hose part number 4663973 is a critical fuel delivery component on the Hitachi ZW220-6 wheel loader. It is mainly suitable for ZW220 series models such as ZW220-6 and ZW220-5A, and is usually used to connect the low-pressure fuel pipeline between the fuel tank and the engine (Cummins QSB6.7 or Isuzu AH-6HK1X), responsible for safely delivering fuel to the high-pressure fuel pump. This universal number is its only original factory identification. When ordering, the complete model number, serial number, and pipeline location (such as inlet or return oil pipe) of the equipment must be provided to ensure that the length, joint specifications, and pressure rating are fully matched.

This product belongs to a multi-layer composite structure oil resistant rubber hose, with the inner layer made of fluororubber (FKM) or hydrogenated nitrile rubber (HNBR), which has excellent resistance to diesel and biodiesel corrosion and low permeability characteristics; The intermediate reinforcement layer is made of high-strength polyester fiber or steel wire weaving, which can withstand a working pressure of 0.3-0.8 MPa and a burst pressure of more than 4 times the working pressure; The outer layer is made of weather resistant and wear-resistant chloroprene rubber or polyurethane. The hose is equipped with standard quick change fittings or clamp type metal fittings at both ends, and the interface specification is usually M12 × 1.5 or M14 × 1.5 metric thread. The working temperature range is -40 ℃ to+100 ℃, which complies with SAE J30 or GB/T 7939 fuel hose standards and is suitable for long-term stable fuel supply of ZW220-6 under vibration and alternating high and low temperature conditions.
